a) (-9+2)*8+56:(-2-4)+7 =
= (-7)*8+56:(-6)+7 =
=(-56)-56/6 + 7=
=(-56)- 9 1/3 + 7=
=-58 1/3
b) -6,3:7 + 3 1/3 : (- 1 1/9)=
= (-0,9) + 10/3 : (-10/9)=
= (-9/10) + 10/3 * (-9/10) =
= (-9/10) - 3 =
=-3 9/10
a) (-9+2)*8+56:(-2-4)+7 = (-7) * 8 + 56 : (-6) + 7 = -56 + (-56/6 ) + 7 = -56 + 7 + (-28/3) = -49 + (-9 i 1/3) = - 58 i 1/3
b) -6,3:7 + 3 i 1/3: (- 1 i 1/9) = -0,9 + 10/3 : (-10/9) = -0,9 + 10/3 * (-9/10) = -0,9 + (-3) = -3,9
